• SQL Server SQL2000 : weird performance event

  We're running a small scale application on SQL2000 SP4 (personal edition) with only 1 user. Got a stored procedure which suddenly takes 7 hours to complete with incorrect results compared to previous runs which only took 5 minutes (and correct results). No problem with other procedures or queries regarding performance. DBCC didn't see any errors. We're able to reproduce the situation (on a different machines) by extracting the code from the production machine (using generate script) using SQL Analyzer/Enterprise Manager. It takes then 7 hours to execute/complete. However, when we take the original script from the developers and recr ...Show All

• Windows Forms Is there a way to programatically control Windows' "Unplug or eject hardware" functionality?

  An example of this functionality is if you have a usb hard drive for example. When you are done using it, it is recommended to double click the "Unplug or eject hardware" icon in the system tray to safely stop/shutdown that device. As .NET can pretty much do anything :), is there a way to control this functionality programatically and automate it. The reason I ask is that when I plug in my usb hard drive, I want it to do a quick sync and then stop itself so I can unplug it right after it's done without harming the data. I have a feeling Windows API calls will be necesssary, so any help you could give would be great! ...Show All

Is there a workaround A command line parameter Something I must do before trying to install Thanks ! Leo, Thank you for the question regarding installation options for the VS SDK. We're puzzled about this problem since we haven't seen it ourselves and have not heard of other reports. To answer your question directly, you can run the self-extracting executable with the -x switch to prompt you for a location to extract to. So this would be ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX Extensions Problem for Visual Studio 2006

  Hello,      I have tried to find an answer for my problem for the past week, and I am not sure if this is the right thread for it.  I have installed DirectX SDK April 2006 with the DirectX Extensions, and I am running VS2006.  When I start VS2006 I don't see the DX extension icon on the intro Splash Screen, but I am able to see it in the About Box for VS2006.  The problem is not that it is justnot loading - or something,  my problem is not being able to debug HLSL code.  If I place a break point in the *.fx file I get "This break point will not currently be hit.

• Visual Studio 2008 (Pre-release) Use of OperationContext.Current for duplex

  Hello In all the samples of duplex the callback is set using OperationContext.Current inside a method called by the remote application. However, this approach requires the client to initiate a call a method on the service before the service can use the callback to send messages to the client. How can I enabled the service to send messages to the client using the callback after the client connects, but BEFORE the client sends anything Simple: store the callback reference somewhere (a linked list, a delegate, etc) and have "someone" on the service side invoke that list at will. I uploaded two demos ...Show All

• .NET Development Preventing .NET DLL execution

  I need some way to prevent my .NET DLL assemblies from being called by unauthorized executables. Is there some way to do that I have tried the StrongNameIdentityPermissionAttribute, but it's not enough. Can be anything, even at low level C/C++ code. I cannot trust in the use of the .NET Framework Configuration tool, because I'll not be an administrator for the systems where the DLLs will be running. But I should constrain the execution of those DLLs by unauthorized executables. You should write a C dll which acts as a password verifier, and then write your code so it requires a password to run ( so the ...Show All

• Visual Studio 2008 (Pre-release) Suggestion for WPF - Navigation Transform

  Hi All I've been checking out the January CTP, and the Sells/Griffiths book, and I'm really excited about WPF...I'm experimenting with translating a Windows Forms app and a different ASP.NET app into WPF, and it's looking good for both! As far as I can see from my explorations, the navigation stuff in WPF just does a straight replacement of the target page in the application. I would love to see transforms between the pages - eg pages displayed on the faces of a cube, and navigating rotates the cube, or pages are arranged in a z-order stack, and navigating zooms through one page to another, or gamma-fade and restore, or flipping around ...Show All
